Well to be expected if the source is an Ero Novel, but usually some of those tend to be short ones (like in the case of this, the novel only being 1 volume long), so there is not much padding they can do to get to the point lolWell that was quick! Big ups to our boi Kaito was just too much of a chad for her. In any other series, he'd be the kind that would have likely bled from the nose and pass out like bitch or run out of the house screaming like he's about to be castrated (also like bitch).
Then again, those series also last longer since the end goal of getting the girls is shafted wayyy into the future of a series (or not at all since the author or someone else in editing wussed out)
To be fair, the art of the maid is cute, id sleep with herBro living the dream
